receiver. The device is functionally equivalent to the
EL16V devices, with higher performance capabilities. With
output transition times significantly faster than the EL16V,
the SY88927V is ideally suited for interfacing with high-
frequency sources.
The SY88927V provides a V
BB
output for either single-
ended use or as a DC bias for AC coupling to the device.
The V
BB
pin should be used only as a bias for the
SY88927V as its current sink/source capability is limited.
Whenever used, the V
BB
pin should be bypassed to the
most positive supply via a 0.01µF capacitor.
Under open input conditions (pulled to V
EE
), internal
input clamps will force the Q output LOW.

NOTES:
1. Duty cycle skew is the difference between a t
PLH
and t
PHL
propagation delay through a device.
2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified
range and the peak-to-peak voltage lies between V
PP
min. and 1V. The lower end of the CMR range varies 1:1 with V
便携式医疗设备的特殊性决定了它们应该是对用户友好的、必须工作在无菌环境下，并且空间占用小、耗能低。 同时，便携式医疗设备还需要足够的计算能力以便处理医疗数据，能够连接到无线或有线接口以便记录和发送数据。从设计人员的角度考虑，上述需求需要低功耗的单片机（MCU）和数字信号控制器（Digital Signal Controller，DSC）。 正是有了嵌入式处理器，设计人员才有可能设...[详细]
